Gig,

Like you, I had not heard of them either, so, I highlighted "Snatcher Fly Patterns" and put it in the search window and Googled it. Several patterns there plus "you tube" tying instructions. They are a very interesting fly pattern and I feel I need to tie up some to "swing" like a soft hackle fly.

Thanks, Mike, for asking the question because I now have another pattern to tie up and experiment with.
